Today I finished up the routing of the two chains that will power the “grass bike.”  The first chain goes around the chainring on the cranks to a rear cassette bolted below.  From that cassette a separate chain makes the long trip to the rear sprocket on the rear wheel.  The central cassette serves as a power transfer between the two chains.  I took it for a test ride around the parking lot outside the welding studio.  Everything seemed to work fine.  Now I will cover it in sheet metal and grass.
